- Insert the needle from back to front through the ch in the corner of the left motif
- Insert the needle from back to front through the ch in the corner of the right motif
- Insert the needle from back to front under both loops of the next st on the left
- Insert the needle from back to front under both loops of the next st on the right
- Repeat steps 3-4 to corner
- Repeat steps 1-2 in corner
